Maybe it's because I am a broke college student. Maybe I just like to find money. When I expect $0.45 and get $0.90, I feel pretty lucky. It's like winning a prize (in a weird way). That's just my opinion.

Now hold on just a minute.
It's true that when I find change in the bin i think to myself "the idiot before me left his change", but I also think "well, their loss, my gain!" and pocket the money.
I'm not so sure that the lucky person says to himself, "wow, what luck" so much as "the idiot that used this machine before me forgot to get his change!"
